POWER SLED' OB SLED ATTACHMENT.

Application filed August 16, 1922. Serial No. 582,186.

To all whom it may concern:

Be it known thatl, JOSEPH M. HoLLowAY, a citizen of the United States, residing at Alliance, in the county of Box Butte and State of Nebraska, have invented new and useful Improvements in Power Sleds or Sled Attachments, of which the following is a specification.

This invention relates to sled-s and has for its objectthe provision of a driving mechanism for propelling a sled over the ground, the driving mechanism being secured to and mounted upon a runner structure and being also capable, by removing certain parts, of being used as an attachment to ordinary sleds.

An important object is the provision of a mechanism of this character which is provided with hand operated means for propelling a driving wheel and also provided with foot operated steering means. I

Another object is the provision of a device of this character in which the foot steering means is adjustably mounted for convenience in use'by persons having legs of different lengths, in other words people of small or great stature.

A further object is the provision of an attachment of this character which is provided with a plurality of adjustably mounted seats one of which is intended for use by the operator and others of which are intended for occupancy by passengers.

Yet another object is the provision of a mechanism of this character in which the rotary drive wheel and also the runners are provided with guards which will operate to prevent the clothing of a-person from being caught which might result in injury not only to the clothing but also to the person. An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy to operate, positive in action, durable in service and a general improvement in the art.

Vith the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in whichm J Figure 14 is a side elevation of the complete device, y I

Figure 2is a. plan view,

Figure 3 is a front elevation,

Figure 4: is a detail cross-section, on the line L4c, Fig. 5,

Figure 5 is a longitudinal section.

Referring more particularly to the drawings I have shown my device as comprising a rectangular frame which includes side bars 10 "connected at suitable points by cross bars 11. This frame may be constructed of angle iron-or wooden beams of suitablesize depending upon the dimensions of the completed mechanism. Upon side bars 10 is slidably mounted a seat 14 for the operator, this seat being slidable forwardly or rearwardly to suit the convenience of the operator. Extending upwardly from the frame at the rear end thereof is a standard 15 which carries an auxiliary seat 16 for a passenger.

The two rear runners, 19, are carried on the extremities of a cross-bar (see Figure 4) which is carried in brackets 17, bolted to the main frame. Secured on the underside of the frame and extending forwardly to a considerable extent beyond the front end thereof is a supporting bar 20' which is supported by the front runner 22. The bar 20 is formed of two sections 23 and 24 formed with a plurality of holes through which pass bolts 25, this structure permitting adjustment as to the length of the support 20 so as to vary the distance of the front runner from the front of the frame.

Pivotally mounted on the main frame as shown at 26 are two rearwardly extending bars 27 which are provided, at their rearward extremities, with slidably mounted bearings 33 for a shaft 29, upon which is secured a drive wheel 31 which has its periphery formed with a plurality of teeth 32. The bearings 33 are held in adjusted position by adjusting screws 84,-. Mounted on the shaft 29 is a sprocket 85. It is preferable to provide a coil spring 36 which is connected with the frame and with the bar 27 for the purpose of normally holding the wheel 32 in engagement with the surface traveled over but yet permitting upward yielding of the wheel in case of striking an obstruction which might result in breaking the teeth.

I also provide a control lever 37 which is suitably mounted on the frame and which is connected with the bar 27 by means of a connecting rod, a bell crank lever and a link as shown in Fig. 1 for the purpose of elevating the toothed wheel out of engagev ment with the surface traveled over as for instance when coasting.

clined supporting structure e2 within the upper end of which is journaled a shaft 43 provided with crank arms 44 carrying handles 45. Secured on this shaft is a large sprocket 46, from which a chain 47 leads under idler pulleys 4:8 and 49 and rearwardly to the sprocket 35.

Secured on and holding the rear portions of the bars 27 in spaced relation is a guard 50 which extends over the toothed drive wheel 81 for the purpose of preventing injury to the clothing or person of the operator or passenger. Extending from the sides of the-frame are fenders 51 which extend outwardly considerably and which will prevent the operator or passenger from getting his feet caught beneath the runners.

In the operation the operator seats himself upon the seat 14, operates the lever 37 to swing the bar 27 so that the wheel 31 will engage the surface to he traveled over. places his feet upon the bar 38 and grasps the handles 45. hen the operator then rotates the shaft 43 by moving the handles 45 by a movement similar to the pedalling of a bicycle the toothed wheel 31 will be driven through the instrumentality of the various sprockets and drive chain. The engagement of the teeth of this wheel with the surface traveled over will cause the device to be propelled, the speed depending upon the speed of rotation of the sprocket 46. Steering is accomplished by swinging the lever 38 in one direction or the other to effect turning of the front runner 22. When coasting down grade the lever 37 is moved to elevate the toothed wheel so that the op erator need not exert a propelling action.

By removing the runners 19 and 22 and their associated parts it apparent that the device may be bolted on to an already existing sled so that it may be considered a power attachment therefor. The various details of the bolting by means which might be accomplished are not set forth asbeing immaterial.

From the foregoing description and a study of the drawings it will be readily apparent that I have thus provided a simple and inexpensive power mechanism for sleds which will be easy to operate and control and which will be of manifest utility and desirability.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1. A power sled comprising a frame, stationary rear runners, a pivotally mounted front runner, a cross bar mounted upon the pivot of the front runner and adapted to support the operators feet whereby to be turned, a seat slidably mounted on the frame, an extendable longitudinally extending bar pivotally mounted upon the frame, a toothed wheel journaled in said bar, a lever operatively connected to said bar by means of which it may be raised or lowered, and

hand operated means for rotating said wheel.

2. A power sled comprising a frame, stationary rear runners, a pivotally mounted front runner, a cross bar mounted upon the pivot of the frontrunner and adapted to support the operators feet whereby to be turned, a seat slida-bly mounted on the frame, a longitudinally extending bar pivotally mounted upon the frame, a toothed wheel journaled in said bar, a lever for controlling the position of the bar and consequently the wheel, and hand operated means for rotating said wheel, consisting of a standard rising from the forward end of the frame, a shaft journaled through said standard and carrying crank handles, a rotary element on said shaft, and an operative connection between said rotary element and said wheel.

3. Apower sled comprising aframe, stationary rear runners, a pivotally mounted front runner, a cross bar pivotally mounted upon the forward extremity of said frame and adapted to support the operators feet whereby to be turned, a front runner secured to said cross-bar, a seat slidably mounted on the frame, a longitudinally extending bar pivotally mounted upon the frame, a toothed wheel journaled in said bar. a lever adapted to swing said bar and raise or lower said Wheel, and hand operated means for rotating said wheel, consisting of standard rising from the forward end of the frame and a shaft journaled through said standard and formed with crank handles, a sprocket on said shaft, a sprocket on the shaft of'said wheel, and a chain trained about both of said sprockets and about idler sprockets in the standard.

In testimony whereof I afiix my signature.

JOSEPH M. HOLLOWAY.
